[Spatial-temporal structure of the primary evoked activity of visual cortex neurons].

The unit activity displayed a mosiac position of the activated neuronal ensembles with asymmetrically inhibited adjacent areas development of primary response. The average distance between the centers of these ensembles, the latter's diameter being less than 240 mcm, was not more than 300 mcm. The centers displayed the most intensive activity of the neurons ranged in a column, with the shortest latency, the greatest synchronization, and the diffuse peripheral area which might be asymmetrical in respect to the center.
